AWNING.

Patented Oct. 27, 1914.

Application filed March 4, 1914.. Serial No. 822,344.

To all whom it may concern Be it known that I, Hans lVnnwATI-I, acitizen of the United States of America, residing at Chicago, in thecounty of Cook and State of Illinois, have invented certain new anduseful Improvements in Awnings, of which the following is aspecification.

My present invention relates to improve ments in awnings and isparticularly designed to provide a simplified supporting frame for theawning.

The primary object of the invention is to simplify the construction andoperation of window and similar awnings, by fashioning adjustable guidearmsor brackets which are operable and. co-act with the awning as it israised orlowered.

The invention consists essentially in certain novelcombinations andarrangements of parts as hereinafter set forth and pointed out in theappended claims.

In the accompanying drawings 1 I have illustrated one complete exampleof the physical embodiment of my invention constructed according to thebest mode I have so far devised for the practical application of theprinciples of the invention.

Figure 1 is a sectional view through a window showing the applicationthereto of my invention. Fig. 2 is an outside view of the window of Fig.1 with the awning fixtures attached. Fig. 3 is an enlarged view of oneof the awning brackets or guide bars of the supporting frame. Fig. 1 isan edge view of Fig. 3. Fig. 5 shows an automatic locking deviceemployed to hold the movable portion of the bracket in the extendedposition assumed when the awning is in operative position. Fig. 6 is anedge view of Fig. 5. Fig 7 is a diagrammatic view showingthe awning whenin lowered posi- .tion.

In the preferred embodiment of my invention I employ two stationarybrackets as l and 2 attached to theright and left sides of the Windowframe 3 by means of the flanges or lugs 4 located at either end. Thesebrackets are made in pairs and are duplicates, except that one may havea perforation, and the other an open slot as 5, as bearings for journaling the pins 6 upon which the roller 7 turns. 1 The roller is journaled near the top of the brackets and is adapted to revolve on itsbearing pins 6 in the bearings, and a shade or awning of usual orsuitable material indicated bythe numeral 8 is adapted to be wrapped orrolled about the roller. It will be understood that the roller suspendedand free to revolve n its hearings and a cord or cable9 which 1s woundaround the drum 10 on the roller in the opposite direction tothewindingof isemployed'to opthe curtain or awning, crate the roller andthrough it the awning. The cable is brought through a suitable openingin the wall of the building. passed over a sheave l1 and may be attachedto a cleat 12 as shown, so that the awning may be operated from theinterior of the buildmg without opening the window as willnbeunderstood.

At the lower free end of the awning or curtain a weighted bar 13 isattached which performs the functions of holding the awn-. mg taut atall tunes and also acts as a guide and retainer when the awnlng isbeing,

lowered or raised.

I11F1g. 3 1s shown the right bracket 1 and inasmuch as the left. bracketis similar in a traveling retainer rod 17 which has a.

movement limited. to the lengthof :the slot 13. This rod has at each enda' forked looking member 18, outside the bracket and provided with endrecesses 19, 19 for apurpose to be described.

In connection with the bifurcated or forked section of the bracket Iemployxan oscillatable or swingingsection 20 which is pivoted at 21 by apin to the bracket 1, and: by mcans of a second pin 22 movable intheguide slot 23 in the fork 14 the radius of the swinging or oscillationof the sectionlis limited. This section is also provided with a slot as241 forming a. continuation of the slot 13' and at its lower end thesection 20 is enlarged to provide a space for the heart shaped plate 25.which is fined by a bridge plate 26 to the scctionQOin proper position,because of its size and shape, to form a loop in the slot which at itsend is closed by means of the spring detent 27. The loop 28 at itsextreme end is bounded by a wall 29 which forms a cam face or edge andthe plate 25 is fashioned with a bearing edge 30 extending each side ofthe ridge or apeX 31 of the cam face 29, and this edge is the contactpoint when the lu'acket section is being raised as will be described.Below this bearing or contact edge and at the side of the apex 31opposite the cam 29 a second cam face 32 is provided, and then the loopreturns to the slot 24- by way of the gate or detent 27.

At 33 a notch is provided for the reception of the retainer rod 1'? andthis notch or recess is located near the lower end of the slots 13 inthe wall of the forked brackets 1 and 2.

it will be understood of course that practically all the parts of thebrackets and operative parts are of metal, and the parts of suitablesize, shape and dimensions.

In operation, when it is desired to lower the awning from the positionof Figs. 2, 8, a, for instance, the cord 9, is loosened from the cleat12 in Fig. 1 and is permitted to slip through the hand as the weightedbar 13, by gravitation, falls and causes the awning to unroll from therevolving roller 7 As the roller revolves it winds the cord on the drum10. The weighted bar 18 descends through the slots 13 and the retainerrod 17 with the automatic locking devices 18 also travels with the bar,but when the bar reaches the lower end of the slot 13 the notches orrecesses 19 of the locking members 18 engage the two pins 21 and 22 andthe movement of the retainer rod is stopped. The weighted bar howevercontinues its descent into and through the slots 24, passing over thedetents 27 and into the loops 28 of the oscillatable brackets. Theweighted bar gradually passes around the first turn of the loop and ishalted at the cam edge 29. The cord 9 is now drawn upon, the roller isstarted to revolve, but the weighted bar is lifted in direct contactwith the lifting edge 30' of the plate 25 and as the pull on the cordcontinues and the rolling or winding of the roller is impeded, theresult, is that the oscillatable bracket is swung on its pivot pins 21to the dottedposition in Fig. 3 and guided by the pins 22 in the slots23. The cord is now tied to the cleat 12 and the load of the bracketsand extended awning is taken at the edges 30 of the plate 25. It will beremembered that the recesses 19 of the locking members 18 are engagingthe pins 21 and 22, but during the swing of the brackets the retainerrod 17 has been brought to the position in Fig. 5 where it is seated inthe: notches 33, and this rod has also retained the upper half of theawning in a vertical plane as in Fig. 7, while the lower half has swungout with the oscillating brackets with the rod 17 as a pivot point. Inthis manner the desired angle and shape to the lowered awning issecured. It will be understood of course that this angle and shape maybe varied by changes in dimensions and locations of parts and suchchanges are con templated.

W hen it is desired to raise the awning, the cord is loosened and thebrackets with the weighted bar swing back to the full position of Fig.3. The brackets may swing back by gravity, and the cord is held taut sothat when the brackets arrive at the position in Fig. 3 the weighted barfalls from the edge 30 down upon the cam edge 32. A continued hauling ofthe cord now revolves the roller 7 and the awning is wound upon theroller, the weighted bar travels up the return side of the loop 28,forces its way past the spring detent 27, into the slot 24, through thisslot into the slot 13 where it picks up the retainer rod 17 and withsaid rod is lifted to the top of the slot 13' the rod being carried intotheenlarged opening 16. The cord is now secured to the cleat 12 and theawning is thus held in raised position.

Having thus fully described my invention what I claim is z- 1.
